Thenpress the band button and see what happens. You will be pleased.GaryIt has also been said that if you remove D15 on the logic board that tx at 420 is possible. The D15 is located on the lower rightside of the logic unit in the center of three diodes. It's marked with a P, you will need to turn the unit upside down to read the P.The modification also work on the Icom IC-T7H, but US version will still be cellular blocked. Here is the frequency range.50 to 200 MHz300 to 824 MHZ849 to 869 MHz894 to 999.99 MHzThis modification is read 1243 times.top of page03-03-2001(IC-T7H) Expand frequncyAuthor: IcomNotice: We can not guarantee specification when expand frequency.How to expand RX frequency●Push [BAND] + [MONI] key while turn ON the power switch.This give you RX 118.0 - 174.0 MHz and 400.0 - 470.0 MHz.How to expand RX/TX frequency.●Cut D15 diode on logic unit. (See below board layout).This give you RX/TX 118.0 - 174.0 MHz and 400.0 - 470.0 MHz.
